A method is provided for operating a compression-ignition engine having a combustion chamber. The method includes establishing, via an injection driver, electronic communication with a primary clock configured to generate a primary time signal. The method also includes commanding an injector to introduce into the combustion chamber injections of fuel having respective pulse widths timed using the primary time signal to generate combustion within the combustion chamber. The method additionally includes detecting a loss of the primary time signal and subsequently establishing an electronic communication between the injection driver and an auxiliary clock configured to generate an auxiliary time signal. Furthermore, the method includes commanding the injector to introduce into the combustion chamber a number of injections of fuel having respective pulse widths timed using the auxiliary time signal and thereby continuing combustion within the combustion chamber. A vehicle employing the injection driver for executing the method is also provided.
